# Agentic payments

> Short reference: two rails (x402 and MPP), path mapping, and openapi.json. Full narrative and endpoints: Accessing Mobula for agents.

The full story — **why agentic payments**, **two rails**, **wallet rules**, and **x402 vs MPP endpoint tables with examples** — is in **[Accessing Mobula for agents](/guides/x402-integration-guide)**. Start there.

This page is a **compact reference** only.

## Two rails, same product

| Rail                                | Prefix            |
| ----------------------------------- | ----------------- |
| **x402**                            | `/agent/x402/...` |
| **MPP** (Machine Payments Protocol) | `/agent/mpp/...`  |

**Path mapping** (same query params; revoke uses **DELETE** on x402 and **GET** on MPP):

| Action         | x402                                 | MPP                              |
| -------------- | ------------------------------------ | -------------------------------- |
| Plan status    | `GET /agent/x402/subscription`       | `GET /agent/mpp/subscription`    |
| Subscribe      | `GET /agent/x402/subscribe`          | `GET /agent/mpp/subscribe`       |
| Top up         | `GET /agent/x402/top-up`             | `GET /agent/mpp/top-up`          |
| Create API key | `GET /agent/x402/api-keys/create`    | `GET /agent/mpp/api-keys/create` |
| Revoke API key | `DELETE /agent/x402/api-keys/revoke` | `GET /agent/mpp/api-keys/revoke` |

<Note>
  **Do not use the same wallet on both rails** for one product — see [Accessing Mobula for agents](/guides/x402-integration-guide).

## Machine-readable discovery (MPP)

[`https://api.mobula.io/openapi.json`](https://api.mobula.io/openapi.json) lists **MPP**-priced routes (including `/agent/mpp/*` and `/api/2/*` where applicable). Details: [MPP Agent endpoints](/guides/mpp-agent-endpoints).
